Arising Zombie Shooter 2D now in Play Store

For the last few months I was working on a top down Zombie Shooter for mobile, based on the Big Rook Games assets for undead empire,
Undead Empire: Hellfire Official Trailer (XBLIG) - YouTube (the project was canceled and they set the assets for free)
so I just wanted to post this, maybe someone has a good idea for updates, new gamemodes, improvements, etc. or just wants to download it
here are a few screenshots, hope you like it!
